摘要： A voltage generating apparatus including a voltage generator and a current splitter is provided. The voltage generator has an output node, and generates a first output voltage from the output node. The first output voltage rises when the temperature rises and the current flowing from the output end of the voltage generator is fixed. And the first output voltage drops when the temperature is fixed and the current flowing from the output node of the voltage generator rises. The current splitter is used for increasing the current flowing through the current splitter when the temperature rises. Therefore, the rise of the first output voltage of the voltage generator will be restrained, and the temperature compensation can be achieved.

摘要： A circuit is disclosed which generates such a bias voltage that when this bias voltage is received by a large plurality of devices of a semiconductor chip, power consumption is reduced in the stand-by mode at any particular operating temperature. The disclosed circuit contains at least one monitor FET, which is kept in its off-state, and which has common properties with the large plurality of FET devices. The temperature dependent leakage current of the monitor FET is sensed, and used to generate the bias voltage in proportion to the leakage current. This bias voltage is received by the large plurality FET devices on their gate electrodes, or on their body terminals.

摘要： A design structure for an apparatus for utilizing a single set of one or more thermal sensors, e.g., thermal diodes, provided on the integrated circuit device, chip, etc., to control the operation of the integrated circuit device, associated cooling system, and high-frequency PLLs, is provided. By utilizing a single set of thermal sensors to provide multiple functions, e.g., controlling the operation of the integrated circuit device, the cooling system, and the PLLs, silicon real-estate usage is reduced through combining circuitry functionality. Moreover, the integrated circuit device yield is improved by reducing circuitry complexity and increasing PLL robustness to temperature. Furthermore, the PLL circuitry operating range is improved by compensating for temperature.
